Answer:
Step-by-step explanation:
General equation of a line:
m is the slope, and c is the y-intercept:
m = 3, and c = 7
Answer:
18 female horses.
Step-by-step explanation:
By proportion 2 : 3 = 12 : x where x is the number of female horses.
12 / 2 = x / 3
2x = 3*12 = 36
x = 18.

Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N

Answer:
1) k = 3
2) 3, 4, 5
3) k + (k + 2) + (k + 4) = 4k
4) 6, 8, 10
Step-by-step explanation:
Jared used the equation;
k + (k + 1) + (k + 2) = 4k
Let's find k.
3k + 3 = 4k
4k - 3k = 3
k = 3
Thus,the integers will be;
3, (3 + 1) and (3 + 2)
This is; 3, 4, 5
He is looking for consecutive even integers but yet got 3 and 5 which are odd numbers. However, he should have used the format;
k, (k + 2), (k + 4) as the 3 consecutive even integers.
Thus, rewriting the main equation gives;
k + k + 2 + k + 4 = 4k
3k + 6 = 4k
4k - 3k = 6
k = 6
Thus,the integers are;
6, (6 + 2), (6 + 4)
This is; 6, 8, 10
Answer: 0.74
Step-by-step explanation:
A= "The person is sick
"
B= "The test gives a positive result"
P(A)=0.03
P(B|A)=0.92
P(B|A')=0.01
P(A')=1-P(A)=1-0.03=0.97
P(B)=P(B|A)P(A)+P(B|A')P(A')=0.92*0.03+0.01*0.97=0.0373
Based in Bayes Rule
P(A|B)=P(B|A)P(A)/P(B)=0.92*0.03/0.0373=0.74
